So...I had my clutch go out on my 2014 Forester on Friday (the pedal stuck to the floor and I could smell burnt clutch). I sent it to the shop and they said I needed a new clutch - not a surprise. What WAS a surprise was that they said I need a new transmission! I only have 80,000 miles on it. I bought it used at 50k, and only have put 30k miles on it. I drive like a freaking grandma, so I'm pretty surprised they said this. Can this really be? Could I really have a bad transmission? Seem so unbelievable to me, but I've sent it to the shop my sis-in-law works at, so I would like to think they are accurate, but I'm having a hard time believing this car has already burned through a transmission! Anyone have any thoughts about this or ways to handle? A friend suggested going by the shop and having them show me the transmission, just so I could get a better idea of what's going on (at the very least). But should I try to take it to another shop? It's in pieces at their shop right now and that seems like a huge pain to get it to another mechanic and it seems like my sister in law wouldn't steer me wrong.... Are the transmissions that unreliable in Subarus? I do drive it in San Francisco, which is notoriously hilly, but... I'm so perplexed by all of this...
